Abstract
Abstract To reveal the dietary ecology of the peregrine falcon (Falco peregrinus), we conducted a molecular analysis for mitochondrial genes (COI and CYTB) to identify the prey species collected from a feeding place found on Sasu Island, South Korea. The results from noninvasive genetic analysis showed that the sequences obtained came from nine species of birds (Cuculus canorus, Eurystomus orientalis, Limosa limosa, Microscelis amaurotis, Oriolus chinensis, Phasianus colchicus, Sterna hirundo, Streptopelia orientalis, and Turdus pallidus). Five of the species (C. canorus, M. amaurotis, S. hirundo, S. orientalis, and T. pallidus) had previously been observed on this island, but the other four species (E. orientalis, L. limosa, O. chinensis, and P. colchicus) were newly identified as present. No mtDNA sequences of land animals such as amphibians, reptiles, and mammals were found in the dietary remains, suggesting that the peregrine falcon preys mostly on other birds rather than on other animals inhabiting Sasu Island. This island has rich avian diversity and abundant animal populations and therefore supplies sufficient dietary resources for the peregrine falcon. Our findings suggested that a DNA-based molecular method may be useful to identify the prey species of these birds and may be valuable in future studies of the Endangered peregrine falcon.
期刊介绍:
Mitochondrial DNA Part A publishes original high-quality manuscripts on physical, chemical, and biochemical aspects of mtDNA and proteins involved in mtDNA metabolism, and/or interactions. Manuscripts on cytosolic and extracellular mtDNA, and on dysfunction caused by alterations in mtDNA integrity as well as methodological papers detailing novel approaches for mtDNA manipulation in vitro and in vivo are welcome. Descriptive papers on DNA sequences from mitochondrial genomes, and also analytical papers in the areas of population genetics, phylogenetics and human evolution that use mitochondrial DNA as a source of evidence for studies will be considered for publication. The Journal also considers manuscripts that examine population genetic and systematic theory that specifically address the use of mitochondrial DNA sequences, as well as papers that discuss the utility of mitochondrial DNA information in medical studies and in human evolutionary biology.
